To ALL WHOM 1T .MAY concerns:

Be it known that I, LUMON B. YALE, of Bainbridge, in the countyof-Chena.ngo,'and State of New York, have invented a new and improvedAdjustable Rocker for Chairs; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art. to make and use the same, reference being hadto the accompanying drawings, formingpart of this specification.v

rJlhis invention relates to a new and improved rocker for chairs, and itconsists in constructing the rocker of metal, cast or wrought, and ofangle-form in -ts transverse section, with a series of holes in it neareach end, to admit of the rocker being securedto the chair-legs furtherforward or backward, as may be desired.

The object ofthe invention is to obtain a chair-rocker which will notonly admit'of being ndjustedas stated, but which will also bc light,strong, and durable. In the accompanying sheet of drawings- Figure "1 isa side view of my invention.

Figure 2, a. plan ortop view of'the same.

Figure 3, a transverse section of the same, taken inthe line :c al, iig.l.

Similenletters of reference indicate corresponding parts. l

A represents the rocker, which may be ofcast or wrought metal, and ofthe usual shape, longitudinally, as shown in iig. 1, but of angle-formin its transverse section, as shown in iig. 2, the tread ,or bottom, a,being of suilicient width toafforde-goodlearing-surface or support forthe chair on the licor, and also to serve, et its upper surface, as asupport o1' bearing for, the legs ofthe chair. This will be fullyunderstood by referring to iig. 3. In the side, b, of. the rocker,near'each end, there is a series of holes, c, through any oi'v whichscrews pass, to-sccure the rocker to the legs, andl it will be seen thatthe rocker may be secured-to the legs further forward or backward, asdesired, by putting the screws through holes c, which are more lor lessforward or backward. Rockers' constructed in this -way will be light,strong, and durable,lnot1iable to get out of repair or become detachedfrom the chair-legs.

Having described my invention, nfhnt I claim as new, `enddesire tosecure by Letters Patent, is-

As a new article of manufacture, a. metallic rocker, A, for chairs, whenmade angular' in its 'transverse section', and provided with n serios ofholes, c, near cach end, as dcscribed,'for the purpose specified.
